Maros Engineering air-operated or pneumatic vacuum valves are used in a wide range of industrial automation applications in systems with vacuum pumps or blowers.

Some examples:

Vacuum packaging of ground and bean coffee and any food that can be stored under vacuum,
Vacuum packaging of sanitary products or textiles such as diapers, mattresses, pillows, etc.
Vacuum plus inerting gas inputs-ex. nitrogen-for the preservation of fresh raw or cooked foods (vegetables, fruits, meat, fish).
Gripping tables in woodworking machines, glass, leather and wherever it is necessary to hold the object to be processed.

Molding plastics and rubbery materials: by means of vacuum it is possible to achieve uniform transformation of the molten product in the molds and give the desired shape to carbon fibers.
Drying treatments: through vacuum it is possible to extract moisture from products or equipment (car/motorcycle brake systems, air conditioning systems, etc.)
Impregnation treatments: vacuum creates conditions for particular substances to penetrate inside the materials to be treated (e.g., impregnation of wood with salts for outdoor use).
